SECTOR: CAR COMPONENT APPLICATION: PAINTING PROBLEM: The realization of a mass production painting plant for coachwork components of big dimensions (1900x1600x800) like plastic bumpers, bonnets and rear doors with the minimum of manpower and with an available plant with low maintenance costs. SPECIFICATIONS: the need to realize the plat into existing premises possibility to use a P+F up-turned conveyor already existing one skid each 90 sec   SOLUTION : The plant has been realized using P+F overhead conveyors System 2000 made of two rings: one slow (1.6 m/min.) for pre-treatments and the other one faster for drying oven (8 m/min). An up-turned P+F conveyor permits the operations of loading and unloading, painting and curing. The use of a P+F overhead conveyor for pre-treatment avoids the products used for pre-treatments damage the mechanical components of the conveyor (trolleys, chain, ect.) The products to be treated, fixed on special supports, are transferred from the up-turned P+F conveyor to the P+F overhead conveyor through an elevator. The products treated and to be painted are transferred from P+F conveyor to up-turned P+F conveyor through a lowerator.
